Determination of flash point – Method for flash no-flash and flash point by small scale closed cup tester

ISO 3679:2022 refers to an international standard that outlines a method for determining the "flash point" of a liquid using a small-scale closed cup tester, essentially identifying the minimum temperature at which a liquid can produce enough flammable vapor to ignite when exposed to an ignition source; it's commonly used for testing materials like paints, varnishes, adhesives, solvents, and petroleum products.
